thanks
so zadig gives WinUSB (v6.1.7600.16385) for both the Bulk Interface (2) and for the Core Driver
no excamation marks on the Device Manager, however I didn't find the Bulk Interface there at all - as that a clue?
I have installed the winusbcompat file as directed
removed my antivirus
still not working 
what next??
I got it. The Bulk Interface was mislabelled as a Generic USB device. Uninstalled and reinstalled with winusbcompat, flashed and ready to rock
thank you
Glad to hear!
for Windows 7 winusbcompat seems to be the only way to get our little salamander working. For me, right click on "Axoloti Bulk Interface", selecting "Update Driver Software" and browsing for "winusbcompat.inf" actually turned the "Axoloti Bulk Interface (Interface 2)" into a "generic USB device" - this seems to be one of the inconsistencies Windows 7 brings along. Try and install MIDI Yoke on it - and it'll have you revert back to the good ole "*.inf"-install method as well (introduced with Windows 95, btw.). I'm setting up a notebook (Windows XP... 
) atm - and everything works like a charm.
Sorry to resurrect this old thread but also trying to install on a Windows 7 (SP1) machine, and am getting this error message when I try and start the Axoloti software:
I can confirm that runtime is saved in the correct place as directed above.
